Ligands allow links: Surface-functionalized anatase nanocrystals self-organize into different nanostructures upon redispersion in hot water. The ligand functionality on the surface of the nanoparticles determines the assembly behavior, allowing the controlled fabrication of highly anisotropic nanostructures. Experimental data suggest that the assembly is directed by specific desorption of the organic ligands from the {001} faces of the crystalline nanosized building blocks (see graphic).
